I found it very difficult to adjust either squelch or volume alone. The stacked knobs are too tiny and close together. So I slipped a rubber washer over the squelch knob. Sooo much easier to adjust now!
COOL IDEA N3GR!!!! I couldn't find the right size washer so I took a toy truck tire and stuck it there.... it is so nice being able to adjust volume and not trash whatr's left of my hearing on open squelch....
